NIGHTMARE. READ THIS BEFORE RENTING. I usually go out of my way to leave positive reviews and occasionally give constructive feedback privately if there’s something that will improve the host / guest experience. After dozens of stays, this is my first bad review. (Airbnb was great in helping throughout the stay).
If you don't want to read the whole review I'll summarize. I’m not saying to avoid Airbnb at all. There are plenty of well reviewed Airbnb listings in Bangkok. Do yourself a favor and avoid this one! The apartment is tiny, the bed is very uncomfortable, the building is not Airbnb friendly and very unwelcoming and the host is... I don't want to be personal so read on.
I’ve never needed Airbnb support in all my stays. During this stay, they were involved 3-4 times over multiple days and multiple case managers. Don’t walk, run!

There was some confusion about an additional guest that was resolved prior to the end of the cancellation period. I ended up offering the host more money for the stay to resolve the issue and the host accepted. A week or so into my stay the host began hassling me again for more money and suggesting that I go to an ATM to pay her cash outside of the Airbnb platform. She did this using a separate messaging app. I immediately moved the conversation back to the Airbnb messenger and brought it to their attention.
First the host brought up the guest issue as the reason. Then the host wanted me to pay the hosts portion of the Airbnb service fees. She also claimed Airbnb hasn’t paid her in past so she would need to be paid in full before I left, which of course I had already paid Airbnb but Airbnb pays the host after check out.
This went on for days with the host sending me lengthy messages and telling me Airbnb had told her I had to pay, which they kept assuring me that they did not. Eventually, Airbnb straightened it out.
During this time the dynamic in the building became increasingly less Airbnb friendly. The building posted signage in the lobby, gym and elevator stating Airbnb was not allowed on that property and that violators would be prosecuted. In addition to the 24hr security the building also started having a police presence in the lobby.
Normally this wouldn’t bother me that much but the feeling was very unwelcoming and being a foreign country I felt very uncomfortable every time we went in and out of the property.
Airbnb brought the issue to the host, who claimed she it was fine due to the length of stay (30 days) being exempt. However, when I asked if she minded if I confirmed that with the front desk she amazingly said that I may be thrown out for asking, possibly have my passport withheld and that I would need to go to a government agency. And that if I was thrown out I would not be entitled to a refund since she had “already told me it was approved”.
It wasn’t easy to deal with, but ultimately Airbnb was great and did an on override the host, allowing us to check out early, issuing a refund for unspent nights. It consumed a lot of my attention and put a negative overtone everything while we tried to continue to enjoy our trip. We then had to find other accommodations which consumed more of our trip.
Then the host accused me of damaging the property by scarring her granite in the kitchen, which we never even cooked in, and that she would have to re-top the granite. I’m not surprised given her behavior. When I pushed back she immediately "forgave me". I have great reviews and rent out my personal home on Airbnb, I always treat peoples property even better than my own.
Like I said, I’ve never needed Airbnb support in all my stays. During this stay, they were involved 3-4 times over multiple days and case managers. Don’t walk, run!
